SASE LOCK.

Application led September 21, 1922. Serial No. 589,569.

To all whom t may concern.'

Be it known that I, MAX OESTERMNG, a citizen of Jugoslavia, residing atCleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in Sash Locks, of which thefollowing is a specification.

This invention relates to improvements in sash looks, and has for itsprimary object thereof the provision of such a lockV that will readilypermit the upper and lower sliding sash members tol be securely lockedin a substantially open position.

A further object of the invention is the provision of such a lock forsashes that when the same are in an'open locked position it will beabsolutely impossible for anyone from the outside to move the lockingbolt to an inoperative position and for consequently raising or loweringthe window other than that originally intended.

It is a still further object of myinvention to provide a sash lock thatis both simple of construction and. inexpensive to manufacl ture and onewherein after the lock is applied to the window the same is not liableto become readily out of order.

With the above and other objects inA view as thenature of the linventionwill be readily understood, the same.k consists y of the novel form,combination and arrangement of parts hereinafter more, fully described,shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designatecorresponding parts throughout the several views,

Figure 1 is a fragmentary elevational view of a window frame disclosingthe sliding sashes positioned therein, the said sliding sashes beingprovided with my improved form of locking means,

Figure 2 is a fragmentary vertical elevational View of one side of theupper and lower sliding sashes, a portionof each of the sashes beingshown in cross section for more clearly disclosing my improved lockingmeans,

Figure 3 is a view similar to Fig. 2 of one side of the lower slidingsash member showing the locking bolt extended to its inoperativeposition,

Figure 4 is a fragmentary transverse cross sectional View upon the linesIV-IV of Fig. 2, but showing the bolt slid to its forward operativeposition, and

Figure 5 is a view similar to Fig. 4 upon the line V-V of Fig. 3.

Referring more in particular to the several views, there is clearlydisclosed an upper and lower sliding sash member 1 and 2 slidablydisposed within the usual window Kframe construction 3. Theside ledge 4of the upper sliding sash 1 is! suitably mortised as at for'receiving afiat like elongated strip of material 6, secured within the side sill byfastening screws 7 or the like.` This flat like strip 6 is provided witha plurality of equi-distantly spaced square shaped openings 8, whichopenings register with similar equi-distantly spaced notches 9 in theside sill 4 for purposes hereinafter more fully described. y

The side sill 10 of the lower sliding sash 2 is provided at a convenientpoint there on with a rectangular lshaped cut-out portion 11 forreceiving a similar rectangular,- shaped box like housing 12, the upperand lower edges of which are provided.v with right-angularly bent flangeportions 13 for engaging within mortised portions of the side sillslO tobe therein securedr by screw fastening means 14. Pivotally secured as at15 to the outer open end ofthe box 12 is a swinging door member 16provided with any preferred type of lockingmeans 17 for securing thecover in The side sill 10 of. the bottom sash 2 is provided' with arectangular-shaped open-r ing 18, within the cut-out portion 11 of thesaid sill, which opening is co-eXtensive with a similar shaped opening19 within the bottom wall 20 of the boX member 12, and in alinement withthe openings 18 andA 19 there is positioned within the box 12 arectangular-shaped sleeve member 21, the inner end of which is suitablyflanged as at 22 for close contact with the bottom wall 20 of the boX 12to be secured thereto adjacent the side edges of the opening 19.

Positioned for sliding movement within the sleeve-21 and opening 18within the side sill of the lower sash is a rectangular-shaped slidingbolt member 23, the outer end of which is adapted to engage in anydesired one of the similar shaped openings 8 in the plate 6 carried bythe upper sill when either one of the sashes is moved to an openposition. Pivotally secured as at 24 and in a manner shown by theseveral views is one end of a similar shaped swinging linkE member 25,the lower edge of which is suitably a locked closed position.

of the sleeve member 21 terminate inwardly' of the similar ends of theside walls, of the sleeve, for permitting the swinging of the linkmember 25, upon its pivot, to a position at substantially right anglesto the sliding bolt 23 when this bolt is drawn to its inoperativeposition.

From the rabove description it `will be 4 readily understood7 thateither the upper or lower sash 1 and 2 may be securely locked in an openposition by merely raising the cover 16 of the boX member 12 at whichtime the link member 25 pivotally secured to the sliding bolt 23 may beswung upon its pivot 24: to assume substantially the position disclosedin Fig. 3, and wherein when the elements are in a position as shown inthis figure the bolt 23 may be slid forwardly to engage in any selectedone of the open ings 8 in the plate 3 and the similar opening 9 in theside sill of the upper vsash 1. When the locking bolt 23 is slid to itsforward operative position it will be readily understood that the shortlink section 25 is to assume a horizontal position coextensive with thelocking bolt and to be maintained within the rectangular sleeve 21 forallowing the swinging door 16 to be again closed at which time it may besecurelyy fastened by the locking means 17. lIt will be furtherunderstood that the diametrically disposed slots 26 within said sleevemember function as a means for preventing total disengageopenings,

ment of the bolt 23 and its associated link 25 from within the boX 12.The outer end of the rectangular-shaped link section 25 may be providedwith any form of finger engaging means 27.

While I have herein shown and described the preferred embodiment of thepresent invention, it is nevertheless to be understood that minorchanges may be made therein without departing yfrom the spirit and scopeof the invention as claimed.

l/Vhat I claim is In a lock for windows of the type coinprising an upperand lower sliding sash,

'the side sill of one of the sash members having a series of equallyspaced openings therein, a boX member positioned in an opening formed inone side sill of the other sash member and having an opening in itsbottom wall alining with a similar opening formed in said side sill, asleeve member secured to said bottom wall in alinement with said a boltand link. pivotally con*- nected at their meeting ends slidablyassociated with said sleeve, said bolt being positioned within saidsleeve with the link folded at right angles thereto and positionedwithin said box when the bolt is in an inoperative position, said boltbeing slid inwardly with the pivot connection and link positioned withinsaid sleeve and the bolt in engagement with one of said openings in thefirst mentioned side sill when the bolt is in an operative *position9 aswinging door secured to sai d box adapted for closing its -open end forthe purpose of preventing the withdrawing of said bolt from itsoperative position, and means for locking said door in its closedposition.

In testimony whereof I affix my signature.

MAX OE STERLING.
